Abstract: INVENTION:  SWIMMING POOL COPING            INVENTOR:   DONALD H. WITTE                   ABSTRACT OF THE INVENTION          A flexible easily installed and low maintenance swim-ming pool coping providing the transitional element between horizontal pool deck and the vertical pool wall.  The coping has a cross sectional profile which uniquely adapts the coping to be coiled for shipping and permits is to he used as a single length around the entire periphery of the swimming pool with a single connection joint.  The coping is secured to the swimming pool wall and may be provided with a pool liner bead receiving groove on one side to secure in place a conventional pool liner. On the other side, the coping has formed an outwardly extending element which may be embedded in and is retained by a concrete deck.  The outwardly extending element is shaped to facilitate unimpeded flow of pourable concrete mix around the coping re-taining element.  The coping cross section is formed to permit it to be readily flexed around small radii in either direction for various pool profiles and to be notched for corners and bent in either direction without need for separate coping corner pieces.

Abstract: OPTICAL DATA RECORD COPIER HAVING ARRAY OF LENSES WITH FIELD GAPS ALIGNED WITH DATA GAPS                       Abstract An optical data record copying apparatus is described which includes an array of lenses whose viewing fields do not overlap the same data group on the master record being copied, and preferably are separated by field gaps.  The viewing field gaps are aligned with data gaps between data groups in the data tracks on the master record to prevent distortion of the copied data.  The optical data is high density digital or analog data, such as digital color television signals recorded on an optical video disc.  The lens array may include a plurality of lens pairs which are separated by a light opaque mask having apertures each aligned with different lens pairs for limiting the viewing field of each lens pair.  One embodiment of the copying apparatus of the present invention employs a fixed lens array and moves the master record and copy so that such lens array scans the entire length of the master.          Another embodiment employs a moving lens array and a fixed master record and copy, such lens array and associated light source being scanned along the length of the master during copying.

Abstract: ABSTRACT OF THE DISCLOSURE     A reservoir for containing liquid medicaments is disclosed.  The reservoir includes a relatively stiff elon-gate channel portion which has an inlet at one end and outlet at the opposite end and which is open at one side.  The channel portion defines a side of the reservoir.  A pair of walls are integrally coupled to the channel portion and extend away from said portion in generally parallel rela-tionship with the open side of the channel portion between the walls.  The walls are sealed together around peripheral regions thereof and define with the channel portion a liquid-tight internal space which communicates with the inlet and outlet.  The walls are resiliently flexible so as to be capable of bulging outwardly to accommodate liquid entering through the inlet, and collapsing inwardly towards one another from said peripheral regions towards said channel portion as medicament is withdrawn through the outlet.

Abstract: ABSTRACT     A method for fabrication of metallic sandwich struc-tures in which metal blanks, preferably of a titanium alloy, are joined at selected areas and expanded superplastically to form a desired sandwich structure.  Various techniques for joining, preferably diffusion bonding, selected areas of the metal blanks are disclosed.  These include treating the metal blanks at selected areas to prevent bonding at those areas and selective application of pressure during bonding.  In the pre-ferred embodiment, the metal blanks are positioned in a stack after being treated at selected areas.  The stack is positioned relative to shaping members and heated to a temperature suitable for superplastic forming and diffusion bonding.  Compressive pressure is applied for the selective diffusion bonding.  The stack is expanded into contact with the shaping members by increasing the internal pressure therein, preferably with inert gas, thus forming the desired shaped sandwich structure in one operation.
